To all whom t may concern.'

Be it known that I, WILLIAM F. MORSE, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements in Mixing- Machines,of which the following is a specilication.

The object of this invention is to provide a new and improved form ofmixing machine which is especially adapted to mix paste or other similarmaterial.

This and other objects of the invention will be fully illustrated in thedrawings, described in the specification and pointed out ,in the claimsat the end thereof.

Fig. 8 is a longitudinal sectional View of the can shown in Fig. 7.

Fig. 9 shows a modified form of fastening the can to the turn table.

In the several figures of the drawings like reference numerals indicatelike parts.

As illustrated in the drawings the machine is mounted 0n the base 1.This base is provided with the brackets 2 and 3 on one side thereof andhas bolted thereto the bracket 4 on the opposite side thereof. Thebrackets 2, 3 and 4 are supported by suitable blocks and 6 for thepurpose of raising the base 1 to a predetermined height from the floor.

The base 1 as shown infFigs. 1 and 2 comprises a cylindrical casingwhich is closed at the bottom and is open at the top. In the center ofthe lbottom 7 of this casing is provided a lug 8 which projects into thecasing andcarries at the top thereof the center pin 9. This center pinhas a shank 10 of reduced diameter which projects into the hollow centerof the lug 8 and is held suspended therein by means of the shoulder 11formed between the pin 9 and its shank 10. As shown in Figs. 2 and 3suitable reinforcing ribs are provided on the inside of the casing,which ribs run radially on the bottom 7 of the casing from the wall 12to the lug 8 in the center of the casing to increase the supportingstrength of the lug 8.

On the inside of the wall 12 are provided the pockets 13, 14 and 15 inwhich are mounted to rotate the antifriction rollersl, 17 and 18respectively. Mounted to rotate on top of these rollers is the turntable 19 whichy comprises a circular plate 20 having j an annular flange21 projecting downwardly at its periphery thereof.

In the center of the turn table 19 and on its under side thereof isprovided a lug 21. This lug has a cylindrical pocket 22 in the centerthereof into which pocket projects the center pin 9.' The turn table 19is provided on its under side with a circular track 23 which rests onthe antifriction rollers 16, 17 and 18 and by which the turn table 19 issupported on the base 1.

The turn table 19 is also provided on its under side with a circularyrack 24 which meshes with the pinion 25. The pinion 25 is keyed to theend of the shaft 26, which shaft is mounted to rotate in the bearing 27formed in the bracket 4, as shown in Fig. 3. Mounted on the outer end ofthe shaft 26 are the pulleys 28 and 29, the pulley 28 being keyed to theshaft 27 and the lpulley 29 being mounted to rotate idly thereon. A belt(not shown) is used to drive these pulleys and may be shifted from onepulley to the other by means of the belt shifter 30. This belt shiftercomprises a rod 31 which is mounted to slide in the bearing 32 and haskeyed thereto suitably spaced apart the depending arms 33 and 34. Thesearms are adapted to straddle the belt and prevent its movement sidewiseexcept when itis desired to shift the belt from one pulley to the other,in which case the arms 33 and 34 are moved to guide the belt onto theadjacent pulley.

The bearing 32 in which the rod 31 is adapted to slide is formed ony theupper end of the bracket This bracket is supported on a sleeve 3G whichin turn engages the rcduced end 37 of the bracket el. A set screw 38passes through the sleeve 3G on-its under side thereof and holds thesleeve rigidly inY place on. the end of the bracket t.

rhebiacket l has a vert-ical extension 39 provided thereon at the endofv which is formed the flange l0. A sleeve ll having a flange 42provided thereon is clamped on top o-f the flange by nieans of the boltsl and rigidly supports the upright lil on top of the extension 39 of thebracket l; the upright il being fastened into the sleeve il to forni anextension thereof. The upright all has an arin 45 clamped to the upperend thereof which arni is provided With'an adjustable sleeve e6. Passingthrough the sleeve and rigidly clamped in place` therein is the pipe e7.rlhis pipehas a reducing nipple S at the upper end thereof into which isfastened the pipe 49 which connects the l 50 with the pipe e7. Aflexible hose 57 is connected to the T 50 at right angles to the pipe bymeans of the union coupling 58, Which hose forms the ste-ain inlet tothe pipe e7. The adjacent opening of the 'l' 50 is plugged up and isprovided with an eye 5l into which engages the hook 52 carried on theend of the cablet. The cable 53 passes over suitable pulleys 5l and 55and carries on the other end thereon a counter-Weight 56 which is usedfor a purpose that will presently appear. v

The top surface ofV thevturn table 19 has the lugs 59, 60 and G1 rigidlyfastened thereto near the periphery thereof. rlhe inner end of each ofthese lugs fornis a groove `with the top surface of the turn table vvithWhich the riin (52 of the can 63 is adapted to engage. The lugs 60 andGl are located slightly on one side of the center of the turn table inthe direction toward the lug 59 to allow the can 63 to be niovcd ontothe top of the turn table until the riin 62 thereof engages the groovesformed by the lugs 59. GO andGl. Asinall post te is then inserted intothe opening `66 provided in the top surface of the turn table in frontof the can. This post has a set screw 67 passing therethrough which canbe adjusted to enga O'e the reinforcing strip GS fastened to theperiphery of the can 63 as shown in Figs. l and 3. In this manner thecan may be clamped between the lugs 59. G0 and Gl and the post 65 on theplatform of the turn table and rigidly heldin place thereon.

After the can 63 is fastened to the turn table 19 in the manner abovedescribed the pipe f7 is inserted into the can 63 and isheld stationarysuspended therein by means of the clamping sleeve -lG as shown in Fig.l. In this position the branch pipe which is G9 connected at rightangles to the pipe ll' at `the Wall of the can.

Leer/,57e

the lower end thereof is held suspended slightly above the bottom of thecan 63s() that the steam which passes through the pipe i7 into the pipe69 can escape into the mixture contained in the can through suitableopenings 7 0 provided on the under side of the pipe for a purpose thatwill presently appear.

Claniped to the pipe Li7 above the branch pipe 69 and suit-ably spacedapart thereon are the stationary mixing paddles 71 72, 73 and 7l. Eachof these paddles comprises a pair of arins 75, having a section 76 of asleeve provided on one'end thereof. A lug 77 projects outwardly fromeach ofthe sections 7 6 in the opposite direction to its arin 75. rlhesleeve sections 76 of each pair of arins 75 embrace the pipe 4:7 and arear# ranged so that one of the arms projects to the right of the pipe andthe other-'to the left thereof. Bolts 78 and 7 9 pass through randclanip the bracket 80 in place thereon.

To hold the bracket S0 firmly in place on the inside of the can 63 twopairs of lugs S-lfand '85 are provided near the bot-toni and top of thecan. Each of the lugs has an angular projection Which forins a shortchannel with Each pair of these channels formed by the lugs 84:- and 85respectively is adapted to receive the enlarged ends 86 and 87 of thebracket 8O and aid the set screw 83 in holding` the bracket 80 rigidlyin place on the inside of the can 63.

The bracket SO has a series of ar is S 89, 90 and 91 integral therewithand projecting at right angles thereto. These arins are suitably spacedapart so that they project into the spaces formed between the paddles71. 72, 73 and 74; as shown in Fig. 5;

ln (l is shovfn a modified vforni of can lll 99 having ratchet likeridges fornied on the i Wall of the can. rl`he paddles 93 used inconnection ivith this can are curved' and are rigidly` heldin place onpipe 47 as shoivn in this gure. This type of can and paddlesinay be usedfor special purposes Where no rotating paddles are required.

Figs. 7 and 8 show stillV another type of can and mixing paddletherefor. The Walls of this can are corrugated as shown at The paddle 94used in coimectionwith this type of can comprises tivo pairs of arrnsv95similar to the arms shown in Fig. 5 and numbered 72, 737 7l, and 7 5.The arnis 95 suspended therein as shown Vin Fig. 5.

are clamped to the pipe 47 in the manner described in i connection withthe arm 71, etc. and are suitably spaced apart. The outer end of each ofthe arms 95 is curved in such a manner that the arms on one side of thepipe curve in one direction and the arms on the other side curve in theopposite direction.

Fastened to these arms on each side of the pipe 47 is a blade96 and 97respectively. Each of these blades is provided with the slots 98 and 99through which pass the clamping'screws 100 by which these blades areclamped to the ends of the arms 95. The slots 98 and 99 permit anadjustment of the blades on the arms 95 so that they can be moved towardor away from the corrugated wall of the can.

When only the mixing paddles shown in Figs. 6, 7 and 8 are used the pipe47 is closed at the `end by means of the cap 101 as no steam is usedwhen the machine is operated with any of these paddles. It will beunderstood, however, that steam may be used in connection with thesepaddles if desired.

The operation of the machine is as follows: l f

The ingredients for the paste are inserted into the can 63 which is thenslid on top of the turn table 19 until the lower edge thereof engagesthe lugs 59, 6() and 61. The post 65 is then inserted into the opening66 provided inthe turn table and the set screw 67 mounted in the post 65is screwed against the reinforcing strip 68 provided on the can 63 so as'to firmly clamp the lower end of the can between the lugs `59, 60 and61 and the post 65. f

The pipe 47 with the paddles 71, 72, 73v

and 74 clamped thereon may then be lowered into the inside of the canand properly heIld y n this gurethe paddles 71, 72, 73 and 74 projectinto the spaces provided between the paddles or arms 88, 89,- 90 and 91on the bracket 80 so that on the rotation of the can 63 to which thebracket is clamped the arms 88, 89, 90 and 91 do not strike the paddles71, 72, 73 and 74.

Power is then applied to pulley 28 to rotate the shaft 27 and with itthe pinion 25 keyed to the inner end thereof. The pinion 25 meshes withthe circular rack 24 provided on the under side of the turn table 19 sothat on the rotation of the pinion 25 the. circular rack 24. and in turnthe turn table 19, is rotated around the stationary center pin 9.

The antifriction rollers 16, 17 and 18, mounted to rotate in the base 1,support the turn table 19 and eliminate unnecessary friction between theturn table 19 and the base 1 and permit its easy rotation thereon. Thecan 63 clamped to the top 0f the turn table 19 rotates with the turntable so that the arms 88, 89, 90.1and 91 revolve around the pipe 47 andbetween the paddles 7 0, 71, 72 and 73, and thoroughly mix theingredients contained in the can. The can is kept rotating until thepaste is properly mixed and ready for use.

Either before or after or during the rotation of the can containing theingredients of the paste, steam may be applied thereto to cook thecontents of the can. This is done by admitting steam through theflexible hose 57 into the vertical pipe 47 and the cross pipe 69 fromwhere it passes out into the paste in the can through the opening 70provided in the cross pipe 69.

After the paste is properly mixed and cooked by means of the mechanismabove described, the clamping sleeve 46 is opened to allow thecounter-weight 56 on the end of the cable 53 to pull the pipe 47 and itspaddles 70, v71, 72 and 73 out of the can 63 and permit the removal ofthe can from the turn table 19 to make room for another can which mayhave been prepared for mixing while the contents in theiirst can wasmixed by the machine.

The bracket 80 with its arms 90, 91 and 92 is disconnected from thefirst can and may be inserted into the next can which is then ready tobe clamped to the turn table and rotated in the manner above described.

When using the can and paddles shown in Figs. 6,7 and 8 the paddles areso adjusted that the contents of the can is forced against the wall ofthe can. The rubbing action of the corrugated wall of the can'thusgradually reduces the lumpportions of the paste.

Instead 0f locking the can 63 on to the turn table 19 by means of thepost 64 and the set screw 67 a ypin 102 may be inserted into the0pening'66 of the turn table. This pin is adapted to make engagementwith `one of the wedge shaped lugs 103vr which are fastened to the can63 on either side thereof as shown in Fig. 9. When the turn table 19 isrotated in the direction of the arrow shown in this figure the pin 102moves up the inclined end of the wedgeshaped lug 103 and graduallyshifts and forces the lower end of the can against the lugs 59, 60 and61 and clamps the edge 62 thereof between these lugs and the pin 103. Tounlock the can 63 from the turn table 19 thc can is given a short twistin the ,opposite direction from the arrow which dis-r engages the pin102- froin the wedge-shaped lug 103 and allows the easy removal of thepin 102 from the turn table.
